Abstract

A wireless communication apparatus includes a body, a first antenna, a second antenna, a sensor, a wireless transceiver, and a switch. Both of the first antenna and the second antenna are disposed in or on the body. The sensor is electrically connected to the first antenna and the second antenna for sensing whether an object is close to at least one of the first antenna and the second antenna to provide a sensing result. The wireless transceiver has a main antenna connection port. The switch is coupled to the wireless transceiver, the first antenna, and the second antenna for selecting one from the first antenna and the second antenna to be electrically connected to the main antenna connection port of the wireless transceiver according to the sensing result.
